This document contains notes from a math lesson on adding integers. It introduces two rules for adding integers: 1) When adding integers with the same sign, add the absolute values and use the common sign. 2) When adding integers with opposite signs, subtract the absolute values and use the sign of the integer with the greater absolute value. Examples of applying each rule are provided. The document concludes with an exercise where students practice adding integers without using a number line.
